Title: Manufacture of semiconductor device
Inventor: OSHIMA TAKU
IPC: H01L21/3205
Filed: 1987-01-14
Abstract: PURPOSE:To form a buried electrode with smaller number of processes and by reducing contamination by evaporating plural materials by a molecular beam by providing a region where the molecular beam is not irradiated on a substrate which has a wave like periodic undulation and by varying an incident angle. CONSTITUTION:A wave like undulation is provided on a semiconductor substrate 1. A lower insulating film 2 is formed by evaporating an insulating material by a molecular beam with an incident angle theta. A buried electrode 4 is made by evaporating a metal material by the molecular beam with an incident angle theta. In this case, the electrode 4 is formed only on the insulating film 2 since theta<phi. Then, the insulating material is evaporated by the molecular beam with an incident angle theta' and an upper insulating film 5 is formed. In this case, the electrode 4 is completely covered with the insulating film 5 since phi>theta'. The electrode 4 is buried by evaporating a semiconductor material 7 by the molecular beam. This enables forming the electrode 4 with smaller number of processes and by reducing contamination.

Abstract: PROBLEM TO BE SOLVED: To improve the picture quality of an object section in a picture rather than the picture quality of a background section. SOLUTION: A video signal from a video camera, etc., is quantized by a quantizer part 105 after the execution of DCT 102, blocking 103 and segmentation 104.

IPC: G01B11/00
Filed: 1988-01-12
Abstract: PURPOSE:To prevent measuring result from being depended upon the characteristic of a track servo by calculating the quantity of the eccentricity of a track by the use of a track position signal indicating the dislocation of the track and a lens and the isometric position signal of an optical disk. CONSTITUTION:An optical head 1 outputs an optical signal (a) to a track position signal generating circuit 2 according to a lens driving signal (d) from a lens driving circuit 5. The circuit 2 converts the signal a to a zero cross signal at a track position and outputs and a track position signal (b) to an eccentricity calculating circuit 3. An isometric position signal generating circuit 4 generates an isometric signal (c) for dividing the number of the rotations of the optical disk into (n) (n is a natural number) to output to the circuit 3 and a circuit 5. The circuit 5 outputs a signal (d) equal in cycle to the signal (c) to the optical head. The circuit 3 uses the zero cross number of the signal (c) and the signal (b) to calculate the quantity of the eccentricity of the track at every 1/2 cycle of the signal (d). This device measures with a state where the track servo is not applied, so that a measuring result does not depend on the characteristic of the track servo.

Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of a viscous fluid stored in a heat generator of a heating device for a vehicle and to accelerate the buildup of heating capacity. SOLUTION: A control device 71 controls on/off of an electromagnetic clutch 51 of a heat generator 16 for a vehicle by compairing cutoff rotating speed variably set according to the water temperature Tx of engine cooling water flowing out of a vehicle engine E to a heating circuit, with the present rotating speed Rx of a driven pulley 53 or a rotor.

Title: Axial thrust reducing device for vertical shaft pump
Inventor: KIMURA JINJI
IPC: F04D13/00
Filed: 1992-01-16
Abstract: PURPOSE:To prevent the blocking of lubricating water caused by the adhesion of marine organisms by providing an axial thrust reducing impeller at the upper part of a submerged bearing in an axial thrust reducing device for a vertical shaft pump of self-lubricating structure. CONSTITUTION:An axial thrust reducing impeller 2 is provided at the upper part of the submerged bearing 3 of a shaft 3. Pressure in the submerged bearing 3 and the back pressure of an impeller 4 are lowered by the suction capacity of the impeller 2. Axial thrust acting upon the impeller 4 is reduced by the lowering of impeller back pressure. Water leak from a casing 5 flows into the submerged bearing 3 from the impeller back face and is pressurized by the axial thrust reducing impeller 2 so as to flow together with pumping water. There is thereby no need to provide the casing 5 with a balance hole, nor is lubricating water blocked by the adhesion of marine organisms.

Filed: 1987-01-16
Abstract: PURPOSE:To simplify the process by a method wherein the resistance of a part of amorphous silicon as a sensing layer is augmented to form the part into an insulating film applicable to interlayer insulation between upper and lower electrode wirings. CONSTITUTION:Contact holes 4 are made on the region excluding the sensing part of an amorphous silicon 3 to expose a part of the first electrode wirings 2 and then after selectively masking the sensing part of amorphous silicon 3, other regions are irradiated with intensive light source for around one hour to form the photoirradiated part into an insulating film by photo-deterioration. Later, the second electrode wirings 5 connected to sensing element are formed into specified pattern on the insulated amorphous silicon to be connected to the first electrode wirings 2 through the intermediary of the contact holes 4. In such a constitution, a part of amorphous silicon 3 is used as the insulating film making it needless to form another insulating film.
